차량경량화를 위한 재료기술의 개발과 적용사례

It is to be classified into friendly environment and safety problems, as a main technology development of the recent automotive industIy. As these tendency, lots of automobile companies focus on a reduction of fuel expenses and strengthen of crash safety using high strength steel. In this study advanced technologies such as tailored blanks, aIuminum extrusion and high strength steel forming applied to bumper beam will be described. As a result of impact analysis and an actual impact test, in terms of beam performance and a possibility for the mass production will be discussed.
